Hello Friends, I have a problem with the range of my Radiolink AT9S remote controller. My drone has a Radiolink R12DSM receiver module. In the tests, the RSSI drops below 20% after 300 meters in the open area and the drone cannot respond to the commands from the controller. They wrote 4 km control distance in the manual. The photo shows the location and shape of the receiver antennas. Why am I getting such low control range?
